Ive noticed that it really doesnt matter how cheap a bearing you run, its how you keep it lubricated is what really makes a difference, especially on chassis bearings. Every single one I buy, I always pop the dust seal off and fill it with grease, and put the seals back on. Ive noticed that even the high quality bearings only come with barely enough grease to notice its there. But like DC said, its always best to buy the best quality bearings you can find on major components like the crank, tranny, balancers, etc.
